    Default CNI OEM Head 300mW from Kvant Spectrum 1.6

    Hey guys,

    I got two Kvant Spectrum 1.6 projectors which were limited in the power to about 500mW in total.

    Now I want back to the original full power. Red and blue are easy, the problem is, that I haven't found a datasheet or a description of the pots on the 532Nm dpss driver board.

    Has anyone some information for me?

    Hi,
    I have the same driver board for MGL-H 500mW heads
    The Diode current pot is "LD RP1" nearest to the DC input
    IIRC it works in counterclockwise!
    Beaware to not overdrive your IR diode.

    hi,

    can you take a detailed picture from the pcb? In my driver, there are some resistors not original anymore...

    I don't see any replaced resistor.
    Or can you explain what is the 'original resistor' please?
    My drivers are exactly the same as yours.
    I've bought the modules from Norty303
    My phone /camera is broken so i would rather show you an older not really detailed photo .
